It's possible that the rule depends on whether the
following consonant is in the same syllable. Maybe
the exact environment is very specific. Perhaps there
are several rules that can cause o>u such as:
o>u/:
C+sonor_C+back$
C+sonor_C+round
C+round_C+sonor
These are just examples; I'm not familiar enough
with the evidence to make any definite rules.
Especially since it's possible the rule is optional,
it may be impossible to make any definite analysis.
